And they were all out in Westwood, Calif., last night to celebrate the L.A. premiere, along with Adam's wife, Jackie, Andy Samberg, David Spade and Milo Ventimiglia.

The movie is about the father-and-son relationship between Donny (Sandler) and his son, Todd, played by Samberg. Donny raised Todd by himself until he was 18 and he hasn't seen him since… until now! We can't wait to see the crazy hijinks when Donny decides to invade Todd's world!
